          Answer This Question

          A:  Hello. It could be the unit is going into an error mode either due to an issue with the alarm or because it has debris in the smoke chamber. Try blowing out the alarm very well with compressed air around the back side edges of the alarm. If that doesn't resolve the issue, please call us with the alarm in hand at 1-800-880-6788 so we can get that resolved for you.

                    Q:Does this type of alarm/detector have to be hardwired or would battery operated be sufficient?

                    1 Answer
                    Answer This Question

                    A:  Hello. This alarm is battery only and can not be wired in. Check with your local authority requiring smoke alarms to find out exactly what kind of smoke alarms you are required to have and where you are required to have them. This is usually your local fire department, local fire marshal's office, or local town government.
